There was a score, no, twenty-three, of us older teenagers, chaperoned by
my sister-in-law, on the sandy shore. I had the real hots for her, I can
tell you—if she was five years older’n me. I saw that she had begun
to sniff the air and look odd.

"What'sa
matta, Sis? You look sick." I thought she was suddenly dizzy. I really
didn’t want her being sick so that my party would be spoiled for her.

"Walt, come
up to the house with me, soon's we can." she murmured into my hot, hot
ear. "Fake a cut, or a splinter. Then ... it would look like I was helpin’..."

"I got
ya, Sis," I whispered back, "O K!

"Oh,
hell! I've got a splinter in my foot!" I muttered after a few minutes.
"I'm gonna go up to the house to see can I take it out, 'n' put somethin’
on it."

There was
an odd smell in the air, not like marsh gas, but like...sexy sweat, sorta.
No one looked up, they were all busy trying to make out.

I started
across the beach, limping almost too much. As I passed Sis, she said,

"Walt, I'd
better help you up to the house; wait a sec".

I helped
her up and I smelled her damp bikini—and something else; she smelled like
summer sunshine, heat and—that odd scent.

Sis "helped"
me over the knoll, until we were out of sight in the big house and on
the second floor, into the suite Leila and my brother had. They even had
their own kitchen and livingroom. Grandmum and Grandad had never let me
go in there while my brother was away, but Sis said, when I hung back,
"Come aw-n, all I'm doin' is helpin' you get a ‘splinter’ out of
your foot! The bandages are in here. Besides, Gammie and Granda are away
for a month, 'n' Gene's out of the country—’n’ it’s your party, ‘n’ I’m
in charge, right?" She grinned, and I felt real warm.

"Yeah, Sis,
right. Don't think any of the gals and guys'll come up, do you?" I asked,
hopefully. She grinned.

"Not
with the booze I left down there, they won't. I saw Cherie and Ralph find
it and let the rest know! If they want to pee or make out they’ll go in
the bushes!" The way Sis said that made me think she'd planned this. That
got my prick even harder. She was kneeling in front of me, pretending
to look for the splinter, I guess, her head down. I could see the tops
of her rounded breasts, all but the nipples. She looked up at me, a strange
look on her face.

"Walt, I
really feel sorta—funny. Did you smell anything strange at the
beach?" she asked me, licking her lips a little. I saw one hand sneak
to her crotch.

"No—yeah...I
did! Sis, it's just...well...are you...kinda ...real bothered, like
me?" I rubbed on the bulge in my trunks—couldn't help myself, I was so
horny.

"Yeah, brud,"
she said, shaking her head a little, "I am kinda...hot. There was some
kinda smell that made me feel really...funny...just before I told you
to fake the splinter. So you smelled it?" She leaned even farther forward,
her bikini top falling away from her breasts. I could feel my rod pulse
with desire. I know she did that deliberately.

"Geez, Sis
... God! you have pretty breasts! Can I..?

"D’you wanta
...? 0! yes-s-s.." She slipped off the bra part of her bikini and sat
up extra straight. I leaned forward and almost fell off the chair. Sis
caught me, hauled us upright, and hugged me real tightly, her hands on
my buns: as she did so she rubbed her pubes against me, and she felt my
hard-on. She grinned again, really teasing us both, I guess.

She was kneeling,
just like that, licking all around the tip, and great God, how good that
felt. I saw that she was fingering herself around the bottom of her bikini
again.

"Can I—do
sompin’ more for ya, Sis?" She took her mouth from me, but held onto the
base of my cock. We were breathing hard. "N-not yet, not...quite...yet,
but try lickin' me, too, if you want."

That was
dumb, but I guess we were both so excited by then that she didn't think
that I'd have a hell of a time getting to her tits with her sucking at
my cock! Then I had another think about what she’d said. I lowered myself
to the floor (Sis didn’t stop licking and sucking!) so I could lie down
on my back; then I wriggled around and she put her knees on either side
of my chest, still sucking on my prick, and I pulled her bikini strings
loose, and her butt down to me. Sis had really nice pubes, with puffy
lips. She was already wet as I started to lick her. Her pubes were shaved
and I could lick her lips and inside them without hair in my mouth—golly,
she tasted good! When I touched her clit, she began to move her hips so
that I had to move my head to keep up with her, and that made my butt
move...and...she moaned and said,

"God! Walter,
I've waited so-o...uh-uh-u-h...I'm comin' a’ready, I’m comin', oo-h, Wal',...that’s
good, u-h-u-uh!" I felt moistness all over my face and licked and licked
at her some more. My prick was about ready to explode when she said, "Turn
around, quick, Walt! No matter 'fyuh come in me, the babe’d look enough
like Gene...damn’ guy can't get a hard-on when he’s home!" I didn't realise
what she’d said until I had slipped my dong deep inside her, and my tongue
was busy wrestling with hers. I pulled back a bit from her face, seeing
to my surprise, but with no slackening of the building excitement within
me, that she was crying. I licked at her tears, and she suddenly smiled.

"Oh, Walter!
You're such a love! Don't tell anyone about Gene cheat’n on me, please!
You must like tasting my cunt, 'cause you're really good, you're soft
and gentle. Do it some more after we...ohmigod...I’m gonna...again, Walt!
I'm gonna ...I...I’m...com’min’ a-ga-a-ain ... push hard, bang into me...fuck
me...hard...come...oooooh! Uhl Uh! Uh! Oh, so go-od," she said, as we
climaxed, then finally relaxed in each other's arms.

After a bit
she chuckled, "Migod, Walt, we never got off the floor!" and she started
laughing. She wriggled herself free of my leg—I was pooped—and helped
me up. There was no sign of our activity, thank God.

"C'mon in
the shower; remember the splinter? We've gotta wash that off, Walt, my
boy ... and a whole lot of other things, too! But you're a damn good fuck,
little brother, ‘f you are only seventeen."

"You know
I'm older’n that, Sis! You even gave me a birthday present."

"What? I
didn't know I gave you...shoot! I didn’t give you any present!" She looked
at me suspiciously. The bulb lit, "Aw, you are a tease! Yeah, I guess
I did.

"Come on,
dry off, I'll put a Band Aid on. Which foot did you limp on, d'you remember?
It might get hurt again! You better believe there'll be a next time, buster!
You're too good to waste!"

Sis had me
a hard on again, just the way she smiled and rubbed against me. She was
still as hot and bothered as I. We finally got into our swimming things,
although every time I started for the stairs, she kept interrupting me
to kiss me, and I kept unfastening her bra to lick her nipples! They stayed
hard, still, like my dick. I really wanted to go down on her again, and
she must have wanted me to, so we got on her bed and she was sucking me
while I sucked on her clit. Took longer, but when we came! Boy!

We had to
go back, though. We’d been gone a helluva time, and the other kids’d be
wondering what we were doing. Actually, they were probably doing exactly
what Sis and I had been doing. I think Sis thought so, too, ‘cause she
grinned a lot as we approached the beach. There was laughter in her voice
as she hollered, "Here we come, ready or not!" She broke out
laughing, and so did I. "Ready or not!"
